HB 5519 introduces prior approval requirements for rate changes in residential property and personal automobile insurance. Insurers must submit rate filings if they propose increases or decreases exceeding 5%, and these rates cannot take effect until reviewed by the Texas Department of Insurance (TDI). The Insurance Commissioner must approve or reject filings within 90 days, considering factors such as insurer solvency, expenses, loss experience, and investment earnings. The bill allows for revocation of previously approved rates if new financial conditions justify changes​.
